Gravitational redshift as a quantum channel: modeling the effects of gravitational redshift in quantum optics
Thomas Mieling, Andreas Wolfgang Schell, David Edward Bruschi
The gravitational frequency shift of light is well understood in the theory of classical electromagnetism. Nevertheless, its description in quantum theory is not yet fully develope…
Fingerprinting Defects in Hexagonal Boron Nitride via Multi-Phonon Excitation
Pablo Tieben, Andreas W. Schell
Single photon emitters in hexagonal boron nitride have gathered a lot of attention due to their favourable emission properties and the manifold of possible applications. Despite ex…
Quantum memories for fundamental science in space
Jan-Michael Mol, Luisa Esguerra, Matthias Meister +4
Investigating and verifying the connections between the foundations of quantum mechanics and general relativity will require extremely sensitive quantum experiments. To provide ult…
Introduction to gravitational redshift of quantum photons propagating in curved spacetime
Luis Adrián Alanís Rodríguez, Andreas Wolfgang Schell, David Edward Bruschi
Gravitational redshift is discussed in the context of quantum photons propagating in curved spacetime. A brief introduction to modelling realistic photons is first presented and th…
Gravitational redshift induces quantum interference
David Edward Bruschi, Andreas W. Schell
We use quantum field theory in curved spacetime to show that gravitational redshift induces a unitary transformation on the quantum state of propagating photons. This occurs for re…
General solution of the time evolution of two interacting harmonic oscillators
David Edward Bruschi, G. S. Paraoanu, Ivette Fuentes +2
We study the time evolution of an ideal system composed of two harmonic oscillators coupled through a quadratic Hamiltonian with arbitrary interaction strength. We solve its dynami…
